COLD ROLLED STEEL Cascadia Metals carries a complete inventory of Cold Rolled Steel products. Cold Rolled Steel is essentially hot rolled steel that has been processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or temper rolling. This process will produce Cold Rolled Steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products. Cold rolling increases the strength and hardness while decreasing ductility of steel by rolling it at ambient temperature (or below its recrystallization temperature). In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product. Product Benefits Cold Rolled Steel offers a number of benefits as compared to hot rolled steel, including... Dimensional Accuracy – Cold Rolled Steel is more precise dimensionally than a hot rolled product created by the hot rolling process. The Cold Rolled Steel has already gone through the cooling process, which helps it remain closer to the finished dimension requirements. Improved Strength & Hardness – the cold rolling of hot rolled steel increases the strength and hardness while decreasing the ductility of the steel. When a metal is cold rolled, it is plastically deformed as it is forced between rolls. This deformation causes dislocations of atoms within the metal causing them to over-lap each other and increasing density. Increased density means greater metal strength and hardness. Superior Surface Finish – the finish on Cold Rolled Steel provides a uniform dull surface that is smoother than hot rolled and suitable for painting or lacquering. www.cmetals.com 1-888-738-9677 CAN / 1-800-997-8660 USA

Surface TreatmentsAnnealing - Cold Rolled Steel can be partially or fully restored to its original properties through an annealing process. Annealing consists of heating the steel to above the recrystallization temperature, soaking at that temperature and then cooling the steel. Heating of the steel during annealing facilitates the movement of iron atoms, resulting in the disappearance of dislocations as well as the formation and growth of new grains of various sizes. The three stages of annealing are recovery, recrystallization, and grain growth.
ASTM SpecificationsASTM Designation A568 outlines the general requirements for Cold Rolled Steel. Included in this specification are steel chemistry requirements and typical mechanical properties of various metallurgical grades.

End-Use ApplicationsCold Rolled Steel coil is produced as a feedstock for metallic-coated coils such as galvanized or galvannealed steel. Cold Rolled Steel has an improved surface finish which makes it ideal for use in furniture, appliances and other consumer goods. Cold Rolled Steel can also be powder coated for post-paint applications.
Other applications of Cold Rolled Steel include automotive, railway components, construction and building components, storage racks, grain bins, partitions, HVAC intakes/exhausts as well as electrical goods. Cold Rolled Steel is also frequently used in construction of bridges, highway products, transmission towers and poles, and various types of equipment.
